Water

Explanation: A compound can be defined as the bonding of two or more atoms, where at least two are different types of atoms. That is, they are atoms from more than one element. Water fits this definition as it is the bonding between two hydrogen atoms and one oxygen atom, with chemical formula H2O. Iodine and gold are elements and therefore are only single atoms. Sand is classified as a mixture and therefore is not the correct option.

Mark it brainliest if im correct :)

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters

Aneli [31]

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

$P.V=n.R.T$

Where:

$P=2 atm$ is the pressure of the gas

$V$ is the volume of the gas

$n=1.5 mole$ the number of moles of gas

$R=0.0821\frac{L.atm}{mol.K}$ is the gas constant

$T=35\°C+273.15=308.15 K$ is the absolute temperature of the gas in Kelvin

Finding $V$ :

$V=\frac{nRT}{P}$

$V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}$

$V=18.97 L$

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters

Gases are measured in different units. Which of the following measurements of pressure are equal? Select all that apply.

viva [34]

Explanation:

Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.

1 atm = 760mmHg

= 760torr

= 101325Pa

= 101325Nm⁻²

1mmHg = 1torr

1Pa = 1Nm⁻²

101.325 kPa and 101,325 Pa are the same

1000Pa = 1kPa

101,325 Pa and 1 atm

1atm and 101.325 kPa
